This can vary from person to person.
If your registration is current, you will maintain the time you have left.
If your registration is expiring within 120 days, you can choose to renew the registration at the same time you obtain your puffin plate.
If your registration is expired, you will be required to renew your registration before or at the same time you obtain your puffin plate.
See DMV’s website for registration and applicable county fees.
For plate transfers:
If, after you obtain the plate, you want to move it to different vehicle that is also in your name, there is a $30 plate transfer fee.
If the vehicle it is being transferred to is not in your name, it can still be transferred but the owner of the vehicle that is receiving the plate will need to pay the plate transfer fee and all original registration and surcharges again.
See DMV’s website for more information about plate transfers.
